Definitions

  • the present invention patent application consists as indicated in a "PERFECTED PANORAMIC VERTICAL WIND TUNNEL", whose new construction, conformation and design features fulfill the mission for which it has been specifically built, with maximum safety and efficiency.
  • the invention relates to a wind tunnel whose effects for the purposes for which it has been designed takes place in its vertical part, that is, the air currents generated by the appropriate means converge in a vertical area being the purpose of the same, that the air flow is capable of lifting objects in said vertical zone, at the same time that said lifting can be visualized from the outside when said vertical part has been constructed in translucent materials, which allows said visualization as well as the measurement of them, to be able to see and measure the rise of the bodies through said conduit.
  • the invention achieves progress in the state of the art thanks to one:
  • Another purpose of the invention is that which will allow the installation of said wind tunnel for recreational activities, so that the general public can enjoy the ascent of the bodies or persons introduced in said vertical part and check how they ascend through the Same, and experience new sensations.
  • Another advantage of the invention is the geometric and spatial design of the different parts of the tunnel to the object in the first place of achieving maximum performance with a minimum consumption of the propellants that generate the air currents and on the other hand that
  • the actuation means of said propellants are located outside the tubes, whereby they do not interfere with the air currents generated by said propellants and do not cause load losses interfering with said air currents, generating in turn turbulence and an increase in consumption of the electric motors that drive the thrusters.
  • the power required for the operation of the wind tunnel is also a dependency in terms of its design, it is therefore not possible to separate both but that the optimization of the formal characteristics will finally be in favor of a decrease of said power, for the same flow and air pressure of said flow.
  • the recommended invention is formed by three ducts that are looped together at their ends in a vertical portion; said vertical portion is preferably formed by translucent parts.
  • the loops are formed by different sections of conduits joined together by the corresponding flanges, seals and means for tightening them, such as screws and the like.
  • Three of said portions of ducts, inside include a propeller that is driven from the outside of the duct by the corresponding electric motor, the motor shaft being connected to the propeller shaft by means of belts, chains, reducing means or technical equivalents.
  • the tunnel model resulting from the invention is essentially constituted by the following sections: - Flight chamber, which is the section of the vertical wind tunnel in which the users of the same will remain, and the place where the current reaches its speed maximum
  • Three return circuits which include a series of straight and curved sections whose mission is to conduct the current from the exit of the flight chamber to the entrance of the corresponding nozzle or contraction, with the minimum possible losses.
  • the technical conception of the tunnel is oriented to the fact that with the help of the air currents generated by the propellers and their motors converge in a zone, the lower zone of union of the tubes, so that the sum of the air flows and the pressures generated by said currents converge in the lower part of the union of said ducts and become a stream of ascending air, capable of lifting bodies introduced in said vertical zone and allowing its movement inside.
  • Tunnel optimization comes by computer simulation of its aerodynamic behavior. This simulation has been carried out using finite element software and has allowed the individual design of each of the tunnel parts. Different configurations have been studied for each of the sections, checking their effect on the air flow inside them in order to reduce turbulence and avoid the appearance of eddies, especially in the more curved areas of the design. The result of this optimization is to reduce the consumption of the propellants necessary for the operation of the tunnel, a crucial parameter to guarantee the viability of a large installation such as the one designed.
  • PCT Patent WO 2004/022427 is shown as "Freefall Flight Simulator", which comprises a compression chamber at the bottom of which emerges from a central nozzle. terminals of a plurality of fans arranged in a centripod configuration.
  • Figure 1 is a perspective of the tunnel (10) and its conduits (11), (13), (14) and upper (20) and lower (19) meeting areas, all of them forming the loops.
  • Figure 2 is a top plan view of the tunnel (10) in which the radial arrangement of the ducts (11), (13) and (14) can be seen.
  • Figure 3 is a perspective view of one of the arms or ducts (11), (13) or (14) with 1/3 of the vertical part (23) of the tunnel (10).
  • Figure 4 is a front elevational view of a loop duct (20) of the wind tunnel (10).
  • the tunnel (10) is formed by the assembly and assembly of different pipes joined together, forming loops (28), forming loops (28) a radial distribution separated from each other approximately 120 ° .
  • the angular ducts (11) are mounted in such a way that the upper end is joined by suitable means to a connecting piece
  • (11) are coupled to cylindrical discharge ducts (13), inside which are impellers formed by an electro-motor (17) kinematically connected with the corresponding blades of a fan (24), not shown in the figures, through a reducer (18) and the pulleys or chains that connect the axis of the reducer with the axis of said fan, at the same time mounting at the lower end of the ducts (13), drive ducts (14), either represented in the figures, which converge towards a star-shaped joint piece (19).
  • the design also includes various internal baffles in the tubes, not shown graphically, located in the upper and lower part of the flight zone, specifically in the star-shaped connection pieces (19) and (20), and at the angles more ends of the return ducts (11), whose purpose is twofold. On the one hand, they allow to avoid the turbulence generated in these points by the change of direction in the movement of the air.
  • the deflector located under the vertical zone of the tunnel, or flight zone allows to modify the air velocity distribution in the flight zone, having been designed to cause an increase in the ascending speed in the vicinity of the walls from the flight zone; This is done so that the lift is greater in the proximity of the walls than in the central part of the flight zone, so that, if the user due to his lack of experience in the free fall flight moves involuntarily towards the walls of the flight zone, the velocity gradient produced by this increase in velocity near the walls will move you back to the central area of the tunnel, thus reducing the possibility of accidentally hitting the wall.
  • This effect is shown in Figure 3.
  • the upper part of the tunnel (10) with the lower one and more specifically the area (20), with the area (19) are joined by means of braces (21) in which translucent panels fit (22), which join the air inlet section (25) to the vertical part (23) with the outlet section (27), delimiting the vertical part (23) of the tunnel (10).
  • Said vertical section has a specific shape, being formed by the composition of two cone trunks of different generatrix. In the lower part of the vertical section in a real-scale installation (between 0 and 3 m high) the cone increases its diameter from 5 to 5.4 m, so that the walls form an angle of 3.81 ° with the vertical, while that in its upper part (between 3 and 8 meters high) the diameter increases from 5.4 to 7 m, the walls forming an angle of 9.09 °.
  • This change in the divergence of the vertical section of the tunnel is intended to modify the vertical distribution of air velocities to achieve a variation between 70 and 50 m / s expertly in a section of reasonable height. Otherwise, the installation would considerably increase its total height, with the consequent increases in construction and operating costs, since the greater the air path inside it would also increase the driving power necessary to maintain a stable flow.
  • the tunnel (10) thus presents a geometry shown in Table 1 characterized by the following aspects:
  • the shape of the cross-section of the circuit is circular in the vertical part of the tunnel, oval in its upper part, circular in the lower part and adopts the shape of a circular sector with a 120 ° opening in a meeting area (19).
  • the entrance section (25) in the flight chamber or vertical part (23) is at ground level, that is its height is Om, and is formed by two cone trunks of different divergence, the divergence of the upper cone being greater than the lower one.
  • the curved sections (11) or corners of the return circuit (26) are angles of approximately 135 °.
  • the return circuit keeps the area of its cross section variable along its entire path.
  • (22) allow the vision of the interior of (23) and the objects or people located inside, without the need for artificial vision elements, being able to convert one of said panels into a practicable door that facilitates the entry or exit of said objects .
  • Table 2 Representation of the vertical velocity values obtained by computer simulation at ground level in the flight chamber (only half chamber is represented). It can be seen that the speed is maximum near the walls.
  • the union of ducts (11), (13), (14), and the zones (19 and 20) is provided by flanges (15) and screws (16) with their corresponding nuts, not shown in the attached figures, intercalating compression joints where necessary, resulting in a closed circuit of great performance and reduced energy consumption.
  • a characteristic common to all the closed wind tunnels is that due to the effect of the friction of the air with the walls there is a heating of the air itself that is inconvenient in a Continuous tunnel operation. While this effect may go unnoticed in a model, it cannot be ignored in real-scale installation since the power supplied to the air in the discharge process is very considerable, and the variation in air temperature would be very significant, especially when the outside temperature is high.
  • the heating of the air produces a decrease in its density; In the installation that is presented this would result in a reduction of the user's lifting force, apart from the discomfort due to the temperature increase itself.
  • the curved ducts (11) are constructed using a good heat conductive material such as aluminum, and to build around a cooling jacket that will be made circulate cold water from a cooling system external to the installation.
  • the interior baffles located in sections (20), (11) and (19) will also be made of aluminum or similar material that is a good conductor of heat, and holes will be constructed so that cold water can also be circulated inside and act as additional heat exchangers.
